Lal Bagh Botanical Garden is a well known botanical garden in Bangalore, India The garden was commissioned by the ruler of Mysore, Hyder Ali.

The garden today houses over 1000 species of flora which include rare and enchanting collection of tropical plants, trees and herbs. The Glass House, modelled along London's Crystal Palace, is the center of attraction in this 2400 acre park.

In July, 2003 it was decided that the Department of Horticulture and Bangalore Development Authority (BDA) would jointly take up the development of Lal Bagh Botanical Gardens.
The garden surrounds one of the towers erected by the founder of Bangalore, Kempe Gowda. Hyder Ali decided to create this garden on the lines of the Mughal Gardens that were gaining popularity during his time. The park has some rare species of plants brought from Persia, Afghanistan and France. With an intricate watering system for irrigation, this garden is aesthetically designed, with lawns, flowerbeds, lotus pools and fountains. Most of the centuries old trees are labeled for easy identification. The Lal Bagh Rock, one of the oldest rock formations on earth, dating back to 3000 million years, is another attraction that brings the crowds.
The Lal Bagh Gardens are based on the design of the Mughal Gardens that once stood at Sira, at a distance of 120 km from Bangalore on the main NH4 at Tumkur District in Karnataka. This is amply supported by ASI .
